124 BRITISH BIRDS. 



A SINGLE Green Sandpiper was put up by me from the banks 

 of the River Dove between Rocester and Norbury, Derbyshire, 

 on July 12th, 1910. This is not, however, the earliest date 

 on which I have seen this species in the district, for on July 

 lOtli, 1908, I flushed another from the side of one of the 

 ponds at Osmaston Manor. There seems to be little doubt 

 that, as in the case of many other waders, these stragglers 

 are non-breeding birds. F. C. R. Jourdain. 



A NEW NESTING-COLONY OF BLACK-HEADED GULLS 

 IN MONTGOMERYSHIRE. 



When my Vertebrate Fauna of North Wales was issued, no 

 breeding-place of Larus ridihundus Mas known to exist in 

 the county of Montgomery. I have just learnt, however, 

 from my friend Mr. Vincent P. Lort, tliat quite recently a 

 breeding-colony has come into existence by the lakes at 

 Llanllugan — a remote spot amongst the hills. Up to this time 

 the Black-headed Gull had only been kno'W'n there as a casual 

 visitor in stormy weather. If unmolested, this new colony 

 wiU doubtless rapidly increase. H. E. Forrest. 



ON THE POOD OF THE HERRING-GULL. 



On July 23rd and 25th, 1910, 1 crossed a patch of marsh where 

 a large stand of Herring-Gulls (Larus argentatus) had been 

 resting and found that their excreta and disgorgements 

 consisted entirely of the shells of immature mussels, although 

 I do not think for a moment that this food is their usual diet 

 for the greater part of the year, but that it varies with the 

 season, as I hope to show later when I have more fully 

 investigated the subject. H. W. Robinson. 



UNUSUAL SITUATION FOR A LITTLE GREBE'S 



NEST. 



The photograph here reproduced of the nest of a Little Grebe 

 {Podicipes fluviatilis) is interesting on account of the unusual 

 situation of the nest. The photograph was taken on May 8th, 

 1910, at Radnor Mere, Cheshire, and shows the nest moored 

 to some sticks rising from the bottom of the lake just inside 

 the entrance to a little-used boathouse. Curiously enough, 

 the only other Dabchick's nest containing eggs on the mere at 

 the same time was in a similar situation — inside another 

 boathouse. The former nest was subsequently destroyed 

 owing to the boat being taken out, but no such misfortune over- 

 took the latter, and the eggs were safely hatched.
